Omaze, an online charity platform that gives anyone the chance to win once-in-a-lifetime experiences that also support social missions, teamed up with the best buds to benefit both the Eastern Congo Initiative -- the first U.S. based advocacy and grant-making initiative wholly focused on working with and for the people of eastern Congo -- and Water.org, which develops and delivers solutions to the global water crisis. Ben and Matt even made a hilarious video poking fun at one another for the cause, which you can see above.

Some of the choicest quips?

That Ben will "bore the s*** out" of his guest with intellectual talk and how "incredibly short" Matt is.
